I agree with the first poster. This image would be much, much better with a more shallow depth of field. As it stands now, the background is very distracting. In fact, just about a killer.e
Another suggestion, stopping motion on the water would also be a huge improvement. When using a smaller f/stop (or technically, a larger aperture), you may also have the opportunity to use a faster shutter speed. You could also try boosting your ISO a tad. Since it's a daylight shot, it won't be too noticeable.
